Auto-sync services from homelab repo via GenServer

ServicesSync polls ~/dev/homelab every 5 minutes: runs git pull, then
re-parses ansible/roles/traefik/defaults/main.yml to derive public and
internal service lists. Services with public_host are shown publicly;
others require internal network access. PageController now delegates to
ServicesSync instead of hardcoded module attributes.
